Summermoon Fire — Suzanne Francis

In the second book of the "Sons of the Mariner" series, a powerful new threat appears in Cloudy Bay, searching once again for the mirror left to Tessa Kivelson by her grandmother.

Tessa and her best friend Jane are cast into an alternative time line. Jakob, Tessa's lover, succumbs to madness, leaving Lut to navigate this confusing new world single-handedly. Will Lut condemn his brother to life in a mental institution while Tessa helplessly floats in the twilight between life and death?

It is Suvi Markku, Tessa's grandmother, who holds the key that will stitch together the ruptured worlds and mend Tessa's broken heart.
